it's not about it being racist. it's about them having racial tensions at the school and trying to keep them tamped down. i think they went overboard. but honestly? i think flying a flag from one's bike is silly and you have to ask why the kid is doing it.
I have to ask why the kid is doing it...why? Why is this any of our business? You gonna ask me why I have a flag on my car?
At some California schools, and from the sounds of it at this one also, kids flaunted the American flag on Cinco De Mayo. Hence the ban on ALL flags.
